redbird | revising, etc.

I'm starting to wonder how much rewriting they're going to ask for. According to one of the people I'm working for/with, the entire prehistory section is "in flux". The latest specific issue is that I've had to add a paragraph on the Aboriginal settlement of Australia. I can do that, and agree that it's reasonable content--but it wasn't in the original list of topics, and it is a bit of extra work.
